Company.com is adding HACMP to an existing pair of nodes. One node is using EtherChannel  with only one adapter. The other node is using regular Ethernet connection to the switch. The customer is going to increase the number of network interfaces to two for each node. 
What other considerations need to be addressed in a HACMP environment?()  

A .  Al interfaces used for HACMP heartbeats must be identical. Differences in the interfaces will cause heartbeat failure.
B .  The network interfaces should all be configured with the same frame type. The use of regular Ethernet frames is mandatory.
C .  Network interfaces for HACMP must be all the same,Ethernet or 802.3. It does not matter which,as long as they are all the same.
D .  HACMP can use any network interface supported by AIX. The options on the various interfaces are masked by the Ethernet switch and do not affect HACMP.

The following statements: CREATE TABLE t1 (col1 INT NOT NULL, PRIMARY KEY(col1)); CREATE TABLE t2 (col1 INT NOT NULL, col2 CHAR(1) NOT NULL, PRIMARY KEY (col1, col2), FOREIGN KEY (col1) REFERENCES t1 (col1) ON DELETE CASCADE ON UPDATE RESTRICT); CREATE TABLE t3 (col1 INT NOT NULL, col2 INT NOT NULL, PRIMARY KEY (col1, col2),FOREIGN KEY (col1) REFERENCES t1 (col1) ON DELETE NO ACTION ON UPDATE RESTRICT);INSERT INTO t1 VALUES (1), (2); INSERT INTO t2 VALUES (1, 'a'), (1, 'b'), (2,'c'); INSERT INTO t3 VALUES (1, 100), (2, 200), (2,300); How many rows will be deleted by the following DELETE statement? DELETE FROM t1 WHERE col1= 1;() 4。 3。 1。 0。 Which presents the heirarchical relationship between LVM entities?() VolumeGroup>PhysicalVolume>LogicalVolume>Filesystem。 PhysicalVolume>VolumeGroup>LogicalVolume>Filesystem。 VolumeGroup>PhysicalVolume>Filesystem>LogicalVolume。 PhysicalVolume>VolumeGroup>Filesystem>LogicalVolume。 采用沼液浸棉种,一般能够有效防治()病。 物质费用反映的是在生产过程中所耗费的物质资料,包括()。 直接物质消耗。 间接物质消耗。 直接人工费用。 间接人工费用。 在大多数企业中普遍存在和被公认的服务与成本的关系是() 在物流服务水平一定的情况下,降低物流成本。 在提高物流服务水平的同时,增加了物流成本。 在物流成本一定的情况下,实现物流服务水准的提高。 在降低物流成本的同时,实现较高的物流服务。
